The present invention is directed to improvements in bullets and is designed more particularly for shooting big game.

The primary object of the invention is to provide a bullet so constructed that it will expand or mushroom progressively in proportion to the resistance encountered and speed at which it is projected.

A further object of the invention is to provide a bullet so constructed that it will not go to pieces or shatter, the construction being such that when the bullet strikes soft flesh, tissues and bone, it will expand progressively according to the resistance encountered during penetration.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of the bullet.

Figure 2 is a longitudinal sectional view through the same.

Referring to the drawing, 1 designates the body of the bullet which is formed from lead and is fitted in a jacket 2 formed from lubaloy, the closed end 3 of which abuts the adjacent end of the body,- as clearly shown in Figure 2 of the drawing.

The jacket 2 is formed with front'and rear cannelures 4e and 5 respectively. nelures 4 and 5 provide front and rear bands 6 and 7, the major portion of the jacket,

or that portion rearwardly of the band 7 being approximately three times as thick as the band 6 and twice as thick as the band 7 The length of the band 6 is such that a portion of the body 1 extends therebeyond and constitutes the nose 8 of the bullet. The length of the band 7 is slightly greater than that of the band 6 and the forward walls of the respective cannelures provide shoulders 9 and 10 against which portions of the body abut. Obviously, the depth and width and length and thickness of the bands 6 and 7, as well as the major portion of the jacket may vary according to the caliber of the bullet, it being essential that the strength The canof the jacket as a whole be increased toward the base or rear portion of the body 1.

When game is struck with a bullet constructed in accordance with my invention and only flesh or soft tissue is encountered, the band 6, being of lighter construction, will, when the lead is forced back upon it, expand under ordinary stress or such resistance as the flesh offers, to the cannelure 5, where it is checked, due to the band 7.

On encountering bone, the band 7 will expand by the stress imparted thereto when the band 6 is forced back upon the body 1. Thus the forward portion of the bullet may be destroyed but the remaining portion functions as a bullet.

The greatest hardness or density of the bullet is at the base, and is lessened by degrees toward the nose, whereby the bullet will expand progressively in proportion to the resistance encountered, this being due to the presence of the shoulders 9 and 10.

Obviously, the jacket 2 will retain the major portion of the body intact and prevent the same from going to pieces. It will thus be observed that when the bullet encounters flesh or bone the bands 6 and 7 will be progressively shifted and the body portion surrounded by said bands expanded or mushroomed but distortion or shattering of the body is positively prevented.

From the foregoing it is thought that the many advantages of the herein described invention will be apparent to those skilled in the art without further description and itwill be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any vide inner and outer bands, said body having a portion extending beyond the outer band and constituting a nose for the bullet, the outer band being of less length and thickness than the inner band, and both bands being' of less length and thickness than the major portion of the jacket.

3. A bullet comprising a lead body having a jacket fitted thereon, said jacket having a pair of bands thereon separated by cannelures, said bands being. progressively ex- 7 pandable under varying conditions of resistance encountered.

In testimony whereoi I afiEiX my signature.
